Does the money reach high-need areas?
Each grant placed by the hardship in its grantee’s ZIP, against the area’s typical level.
US giving: 66% of grant dollars ($4.4B). The need read here covers only this US portion; the 34% that went abroad ($2.2B) is mapped below.
Its human-services grants (FY17–25, $64.7M) land where the poverty rate runs at 14%, against an area that typically sits at 10%. 100% of those dollars go to grantees based in above-average-need neighborhoods. Most of its grants land in higher-need ZIPs.
How this is measured

How this is measured
Who it funds again
Organizations funded in more than one year, against those funded once.
Grantees it renews have grown median revenue +49% since the first grant, against +36% for those funded once.
466 repeat relationships: 247 still active in FY2025, 219 since wound down; 46 grantees were first funded in FY2025 (too recent to call).

414 grantees tracked through their own filings, 2017–2025.
Each grant beside the grantee’s revenue from every source, year by year.
How this is measured
Counted here: distinct organizations funded across 2017 to 2025, not grant rows in a single year, so this will not match the grant count on the cover. 414 of the 842 grantees resolved in that span have returns of their own we could reconcile.
Each grantee is resolved to its own IRS returns. Association, dated; never a causal claim.

Warm introductions · Powered by PlinthPlus
How do I get to The Susan Thompson Buffett Foundation?
Find your warmest path to The Susan Thompson Buffett Foundation through trustees and officers whose names appear on both boards. Search for your organization and Plinth traces the shortest route it can evidence.
Each link is a name appearing on two organizations’ public IRS 990 filings, matched on that name and, where the filings support it, on location. A same-state match has geographic support, which is a second matching feature rather than confirmation that the two are one person; a cross-state one is the likeliest to be two people who share a name. Every hop shows its tier, low-confidence and distant paths are held back rather than guessed, and it is worth confirming the person before you use the introduction.
